Making Physiology Happen


MC-PeakPro Research Grade Metabolic Cart

For Elite Athletes, where every second counts, consider an upgrade to the MC-PeakPro.

The MC-PeakPro system includes everything needed for recording and measuring:

  • Basal Metabolic Rate (BMR)
  • Resting Metabolic Rate (RMR)
  • Respiratory Exchange Ratio (RER)
  • Sedentary to Light Activity
  • VO2 and VCO2
  • VO2 Max
  • Anaerobic Threshold (AT)/ Ventilatory Threshold (VT)

Validation of Metabolic System:
Hutchison AT, Couper S, Mejia A. Validation of the MC-PeakProTM for Metabolic Measures during Rest and Maximal Exercise. JEPonline 2020;23(1):113-124.


The system includes:

  • IX-PeakPro Fitness Assessment module
  • A-CAL-200 Gas Analyzer Calibration Kit
  • A-FH-1000 Resuable 1000L Spirometry Flow Head
  • A-CBT-1011 Clean Bore Tubing
